ASCII - An acronym for American Standard Code for Information Interchange. ASCII files are plain, unformatted text files that are understood by virtually any computer. Windows Notepad and virtually any word processor can read and create ASCII files. ASCII files usually have the ".TXT" extension (e.g., README.TXT).
Binary File - A file that contains data or program instructions written in ASCII and extended ASCII characters.
Bit - A binary digit in the binary numbering system. Its value can be 0 or 1. In an 8-bit character scheme, it takes 8 bits to make a byte (character) of data.
Bytes - A collection of eight bits that represent a character, letter or punctuation mark.
Cable - Transmission medium of copper wire or optical fiber wrapped in a protective cover.
Client/Server - A networking system in which one or more file servers (Server) provide services; such as network management, application, and centralized data storage for workstations (Clients).
DNS (Domain Name System) - A DNS server lets you locate computers on a network or the Internet (TCP/IP network) by the domain name. The DNS server maintains a database of domain names (hostnames) and their corresponding IP addresses. The IP address "188.8.131.52", corresponds to the DNS name www.google.com.
Internet - A global network of networks used to exchange information using the TCP/IP protocol. It allows for electronic mail and the accessing ad retrieval of information from remote sources.
IP, Internet Protocol - The Internet Protocol, usually referred to as the TCP/IP protocol stack, allows computers residing on different networks to connect across gateways on wide-area networks. Each node on an IP network is assigned an IP address, typically expressed as 'xx.xx.xx.xx'.
IP address (Internet Protocol address) - The address of a computer attached to a TCP/IP network. Every client and server station must have a unique IP address. Client workstations have either a permanent address or one that is dynamically assigned to them each dial-up session. IP addresses are written as four sets of numbers separated by periods; for example, 184.108.40.206.
LAN (Local Area Network) - A network, connecting computers in a relatively small area such as a building.
NIC, Network Interface Card - A card containing the circuitry necessary to connect a computer to a particular network media. Typically, the NIC plugs into the computer's accessory bus, (PCI, USB, etc.) and provides a network connection such as 10baseFL (fiber Ethernet), thin-net, AUI, etc.
PC - abbreviation for a Personal Computer.
Ports - is a connection point for a cable.
Protocol - is a formal description of a set of rules and conventions that govern how devices on a network exchange information.
TCP/IP, Transport Control Protocol / Internet Protocol - TCP and IP are communications protocols, that is, structured languages in which data is communicated between one process and another, and between one network and another. TCP/IP is implemented in a multi-level layered structure.
TCP/IP is the 'glue' that ties together the many heterogeneous networks that make up the Internet.
